According to the Remove Mold Guide, mold starts growing in HVAC systems for two primary reasons: moisture and nourishment. The moisture is due to condensation, which typically occurs during warm months. When your house is warm, water vapor can begin to form on the inside of your air ducts as cold air is pushed through them. If there is a high level of humidity in the air, the water will begin to collect instead of evaporate.
Any environment with high moisture is a breeding ground for mold. What makes HVAC systems particularly bad is the air it intakes from the outdoors. With outside particles continuously being pushed through the ducts, dust tends to collect in them. Dust contains organic materials, such as pollen and skin cells. These substances are the equivalent of food for mold, providing it the opportunity to grow and multiply. Add in the moisture that’s typically found in these systems, and it’s easy to see why mold is so common.
